cuticle-TABLE AND KEYBOARD-COVER FOR CALCULATING-MACHINES:AND THE LIKE.

To all whom it may concern:

Be it-known that "FRANK"C. Rinse/nu, a citizen'o'ftheUnited States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented'a certain new and useful CheCk-Table and Keyboard Cover for'Calculating Machines andv the like, of which the following is adescription, reference being had to the accompanying drawings, formingpart of this specification. i

-My'invention has for its object the provision of a'convertiblecheck-table and keyboard-cover which in one positionmay be used as aconvenient support or table upon which. to place checks, sales-slips andthe;

like which are being" added upon the machine and which in another positon serves as a cover and protection for the keyboardot the machine andprevents the accumla when the tien of dust and dirt thereon chine 18 notmuse.

v A furtherand subordinate feature of the inventiom but one ofconsiderable imporpart only of the keys oit' the machine, leavis aperspective view of a calculating ma-. 7 4O ing the remainder (ii-thecover to serve at one and the same'time both as a checktable' andsupport and as a cover for the remainder of the keys; allfashereinafter." more fully explained and particularlypo1nted out in: myclaims;

in the accompany-mg drawings Figure 1 chine equipped with my invention,the checktable and cover being shown in full l1nes 1n the positionoccupied by itvwhen it is being usedboth as a check-table and 'as apartial cover for the keyboard-,'and in dotted lines in the positionoccupied by it whenbeing I used solely-as acheck-table or support; Fig,2 1s a' front elevation, partly in section, of

the parts shownin Fig. 1 Fig. 3 a similar view withthe check-table andcover in the position occupied by it when serving solely as achecktabl'e' or support; and Fig. 4 a. side elevation of the hingedsupporting" arm 7 torthe check-table in folded position against the-sideof the machine.

I The same letters of reference are used to indicate corresponding partsin the several views The combinedcheck-tabl'e andkeyboard cover A ishinged at itslefthand edge to supportsupon the frame or casing of the;calculating machine B, in the present instance to a post C near thelefthand for ward corner of the machine and to a similar but higher postat the rearward leftvhand corner of the check-table, the latter sheetmetal of sufficient size and-proper" shape to fit over and, cover thekeyboard when swung to righthand horizontal posi- 7 tion, and to form acheck-tableor support at the left of the machine, for checks,salesslips'and the like when swung to lefthand horizontal position inwhich latter position it may be supportedby means of a hinged bracket orsupporting arm D, as'shown in This supporting arm D is composed of twoarms'a and b hingedtogether at the middle of the support in such mannerthat the arm ainay be swung around into line with and against the outerface of the arm 7?), when the support is not in-use, and the two beswung upwardagamstor, ad acent the side of the machine and engaged by aspring chp c; as shown in Figs. 2 and 4t.

When the'support D is to be used it is swung outward and its part a isextended into the,

90 itsouter end engages a notched opening d position shown in Fig. 3, inwhich position in the check-tableA (best shown in Eig. 1) the' extremityof the arm a being provided with notches in its opposite edgesforengaging the openingd and supporting the table A in horizontalposition. Whenthe table 'A is not required for use'thesupporting arm Dmay be disengaged from it and the.

machine and engaged by the clip '0; and the table A be swung over intorighthand'hori Y 'may rest and be supported upon posts 6 e from therightside of projecting upward the machine;

arm be folded'up' against the side of the. i

'In the use of calculating machines of this character expert operatorsfrequently employ only the'first five keys in each row, instead of thefull nine, and where the items being added upon the machine are small inamount, as in the case of ordinary sales-slips, for instance, it is notusually necessary to employ more than four or five rows of keys. F orthe purpose of accommodating my combined check-table and keyboard-coverto the use of the machine under these conditions I have formed itsforward righthand portion of a hinged section A, instead of forming theentire table and cover of a single piece of sheet metal, and have soarranged this hinged section that it may be swung backward upon orbeneath the portion of the table at the left of it, to expose only thekeys which are required for use under the conditions mentioned. Thispermits all of the plate A excepting its hinged portion to be employedas a table and support for the sales-slips in convenient relation to theexposed keys, while at the same time serving as a cover and protec tionfor the remaining keys. The hinged section A of the plate A is providedat its rear edge with a narrow projecting flange, indicated in dottedlines at f in Fig. 1, adapted to overlap the front edge of the mainportion of the plate when the latter is swung outward into its lefthandposition as in Fig. 3, such engagement of the flange 7 with the body ofthe plate serving to support the hinged sectionin position in the planeof the body of the plate when the latter is being used in such lefthandposition. A third support 6 for the plate A, when the latter is in theposition shown in Fig. 1, is provided beneath the forward righthandcorner of the portion of the plate beneath which the hinged section isfolded. As will be understood from the foregoing, my invention providesa convertible checktable and keyboard-cover which may be used at onetime exclusively as a check-table or support for checks, sales-slips andthe like, and at another time exclusively as a keyboard-cover for theprotection of the entire keyboard, and which may also be used whendesired both as a cover for a portion of the keyboard, leaving certainof the keys exposed for operation, and as a table and support forsales-slips and the like in convenient relation'to such exposed keys.

The supports for the check-table both the hinge supports for itslefthand edge and the supports upon which its righthand edge rests1naybe of any suitable character and may be secured to the frame or casingof the machine in any convenient way, but a further and subordinatefeature of my invention consists in the means I have pro vided fordetachably securing such supports to the casingof the machine. Thismeans consists of clips a a at the opposite sides of the machine,engaging the projecting head or flange around the upper edge of thecasing, and forming the outer extremities of inwardly-extending sheetmetal strips or arms Z) I) resting upon the top of the casing. The innerends of the strips Z) 7) are upturned and connected by screwbolts andnuts 0' (Z, by means of which, after they have been applied to themachine, they may be drawn toward each other and the clips a a at theirouter ends be securely engaged with the flange or head at the top of thecasing. The two strips 6 7) at each side of the casing are connected bya strip 6 extending longitudinally of the casing and resting upon thetop thereof, the forward post 6 which supports the righthand edge of thecheck-table and cover A being secured to and projecting upward from therighthand strip 0 about midway of its length, and the rear one of saidposts a being formed by a vertical extension of the upturned inner endof the rear clip-strip 7). The forward post C at the lefthand side ofthe machine, to which the lefthand forward 1 corner of the check-tableis hinged, is carried by the clip-strip I) at that corner of themachine, and the rear post, to which the lefthand rear corner of thecheck-table A is hinged, is carried by the rear clip-strip b at thatside of the machine, or by the longitudinal strip 6' connecting the twoclipstrips. The longitudinal strip 6 at the left side of the machine hasformed integral with it a depending arm 6 which extends downward to thebottom of the casing and at its lower end bears against the sidethereof, this depending strip 6 forming the hinge-support for the lowerend of the arm D, Fig. 3. The spring clip 0 is secured to the strip 6above and in line with the depending arm 6 As will be understood fromthe foregoing I have provided a convenient means for attaching myconvertible check-table and key boa rd-cover to the casing of themachine, by means of which it may be readily attached to or detachedfrom the machine, and which requires no special provision upon the machine itself or its casing for such attachment.
